This is only failing when i try to add the api.

Could you run adb -d logcat in a separate terminal and paste the full crash report?

Thanks. Here it is: https://gist.github.com/willrax/ae3054aad0123b4fa210

Could it be that the argument passed to addApi() is nil?

Quite possible, it is a nullobject error. Doing a puts on the object outputs nothing.

LocationServices::API is supposed to be a constant, so im guessing it should be returning something. Though it doesn't return anything.
